Summary :
Editorial : This second teaching bulletin is dedicated to surgical oto-endoscopy. Last November, Professor Jean Marc Thomassin organised the first course in ear surgery under endoscopic control. This gave the Revue de Laryngologie the opportunity to draw attention to this new technique by reporting the experience of the main proponents of the technique, this will allow the reader to weigh up its value in relation to his own daily practice. We are grateful to the company Karl Stortz for its help in the production of this bulletin. Didier Portmann
